چکیده
Web and an Object-Relational Database Management System Alistair Dunlop, Mark Papiani and Tony Hey July 12, 1996 Abstract Reformatting information currently held in databases into Web pages requires signi cant e ort in both creating the pages initially and their subsequent maintenance. We avoid these costs by coupling a Web server indirectly to a multimedia database using additional software we have developed. This software layer translates Web requests for information into SQL queries, and generates Web pages dynamically to display the results to the user. The method we have developed allows users to query the database directly and browse for information.

This paper introduces object-oriented access controls (OOAC) as a result of consequently applying the object-oriented paradigm for providing access controls in object and interoperable databases. OOAC includes: (1) subjects, like users, roles etc., are regarded as firstclass objects, (2) objects are accessed by sending messages, and (3) access controls deal with controlling the flow of messages...
متن کاملA Retrospective on Semantics and Interoperability Research
Interoperability is a qualitative property of computing infrastructures that denotes the ability of sending and receiving systems to exchange and properly interpret information objects across system boundaries. Since this property is not given by default, the interoperability problem and the representation of semantics have been an active research topic for approximately four decades. Early dat...
